if you already know the full entity name, and partition (and you don't
want, on Friday afternoon, to hear my views about partitions), and have
some idea of the time. I guess if you have no idea of the time, you
could say "from the neolithic era until now, every nanosecond". But the
trouble is, the output will be verbose.
What I'm thinking of is like the "directory" command (or perhaps I
should say "ls", as a Unix user), where "show" is like "type" I
*could* find out all the files I have in a directory using the command
"type *".
What I have in mind is something like:
show whats_recorded node4 feric
recorded node4 feric circuit * partition *
start 01-jan-1992:12:0:0
every 1:0:0
until <no end time>
first recording at 01-jan-1992:12:0:01
recorded node4 feric circuit * partition *
start 01-dec-1991:12:0:0
every 1:0:0
until 24-dec-1991
first recording at 01-dec-1991:12:0:01
Obviously I'm not suggesting a specific output format.
Maybe there IS a way to do this. But I haven't found it.

John,
There is no function which gives a list of all recorded data.
The problem to implement such a function is that the particular recording
request can be deleted but the corresponding data are still in the
historical repository. So the only way to look at the collected data is
to scan the historical repository. This is exactly what is done when
you specify Past Time Show.

You don't need to know the full entity name. The Past Time Show supports
any valid entity identifier. You can specify a wildcard as a global entity
instance and in the case when the particular instance doesn't have a
historical data in the specified time interval you receive a corresponding
message.
Now about time format. In your case you should not specify "every".
When you specify "from ... until ..." Past Time Show returns you all
data recorded inside the specified time interval (plus one just before
and one just after).
To decrease the output you can ask not for hole partition but just for
one attribute. PM will filter output for you.
I described how you can receive information you are interested in.
I added the "directory" function to our wish list but doubt that
it will have a high priority.
